You're limited as to what kinds of ships can go into a Landing Craft TF. I almost never use that type of TF for that reason, and putting LC's into an Amphibious TF doesn't affect their unloading abilities at all.

Yes but are there any differences in how these two types of TF operate? I have noticed that if you form an all landing craft amphibious TF and use it for to load supply only, the next turn it will automatically revert to a landing craft TF. That is the computer will not allow it to remain as an amphibious TF.

I would think that a barge TF would unload at a slghtly slower pace but have less over the beach breakage vs an amphibious-but don't really know.
